Chiang Mai is famous for having some truly valley flowers. Most bloom early in the year from January to February. Colorful flowers like African marigold, globe amaranth, orchids, Ban Chun, chrysanthemum, celosia, and assorted roses like Fa Mui and thin Uang Dok Lek. This is regarded as the most beautiful period of Chiang Mai. The celebratory atmosphere and the tradition of locals that enjoy floral beauty since old times are why the grand Flower Festival is organized.
